Dolphin Teeth Fossils SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Cetaceans' closest living relatives are the hippopotamuses, having diverged about 40 million years ago. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetartiodactyla
Man do I love this river! We were the first ones to the beach today and it was a good thing too, three hours later it was filled with folks showing up for the various Easter events at Stratford Hall. On of the first things I spied was the biggest shark vert that I had ever found, and I was feeling pretty stoked about that until my wife let a yell and held up one bigger. My wife did the racetrack pattern along the water line while I settled in for sifting, she ended up doing better than I did, though I did end up getting some cool finds as well. Total haul. Shark verts. Couple of fish verts and an epiphysis. Croc tooth, dolphin teeth, and a crab claw.
This was my first trip to the Potomac in a month, hard to believe it had been that long. What an incredible day on the Potomac it was! My wife had never found a Megalodon tooth before...today she found three! I too got into the action and found my biggest ever, the crazy thing was that they were all found in an area the size of our family room. We also found some large vertebrae, I dug two up while sifting and my wife found one at the water's edge...that one of was identified as coming from the tail section of a whale. There was a tour going beyond the ropes and the leader stopped long enough to provide an identification. Even though we had a banner day on the beach, I was jealous of all the orange vests heading past the ropes to the off limits areas...the grass is always greener on the other side of the fence, eh? I sifted most of the day, I was lucky enough to find a couple of dolphin teeth for my efforts. I also found what is obviously a crab claw, I just don't know if I is a fossil or not...please weigh in. It is hard as a rock but I just don't have the experience enough to tell. Total haul: Megs a little closer. Dolphin teeth. The crab claw...please weigh in on whether it is an actual fossil or not. The vertebrae:
I had originally scheduled today as a day off to go hunting...well, sitting in a tree when it is 80 degrees is mighty uncomfortable and the deer movement is usually nil, so I did a little shark tooth hunting instead. It's been a few weeks since I was at Stratford Hall so I set my sites on there. I would much rather just surface collect but since I'm restricted to the beach, I broke out the screens and sifted. I can't say I got anything too exciting, though I did find my first dolphin tooth which made the trip for me! I also found a small tooth that I'm not sure what it is, I looked through my book and my usual web sites for an ID an I've got nothing. So please help me out, let me know what I found. Total haul: Mako First Dolphin tooth My unknown...finding a tooth with cusps like this here has me confused. It is only a little over 1 CM wide Front side: Back side.
